IMPROVEMENT IN HARROWS.

The Schedule referred to in these Letters Patenc-and making part of the sana."-4

I, J ons S. LEWIS, of Elkader, in the county of Clayton, and State of Iowa, have invented certain new and useful Improvements iu Barrows.

l Nature and Objects of the Invention.

My improvementsI relate primarily to that class or description of. harrows or drags known as side-hill harrows, in which the frame is divided longitudinally,

and its two parts hinged together, so 'as to enable it4v to conform ,to irregularities in the surface of the ground, or to have either side turned up, to avoid obstruction s. The objects-of' myinvention are to simplify the'con-` struction of', and increase the strength of the structure, to facilitate its guidance and control, and to improve its operation.

My improvements consist- First, iu the provls on of 'a conlter, (rolling or sta- I tionary,) near the rear end oi' the ceutre-bar;

Description of Dra-wing.

The accompanying drawing represents a perspective view cfa hill-side harrow,emhodying my improvements.

General Description.

In said drawing- A represents the centre bar or hearn;

B B, the side bars;

C, the teeth;

D D E E; the links or braces, connecting the side barsB tothe cen'trebar A;

F G, the pivotal pins in the ends of the centre bar A, for the attachment of the liuks'D E thereto H, the co'nlter;

I, the guiding-handle;

J; a standard, for the support of vthe handle I;

K, the clevis; and Y L, a chain, for attaching thc draught to the cle`- vis K.

The centre bar A may be made with a portion, a, of metal, for the support of the coulter H, or entirely of wood, and toenable a close joint with the sidelbars B, at the front end, it may be rounded off, as shown, or be of uniform form throughout.

rlhe side bars B are preferably made entirely of wood, and rectangular in cross-section, as shown, their front ends being bevelled on the inner'side as shown, to,

enable closer contact with the centre bar A, at that point.

The teeth C may be constructed and secured in place in any usual or suitable manner, being arranged entirely in the side bars B, or partially (one) in the centre bar A, as shown.

The links D E maybe made of wrought-iron. The former are preferably att-ached rigidly to the Afront ends of the side bars B, being bent in conformity with the inner faces of said bars, having their Outer ends d at the proper angle, and peribrated furthe reception of the pivotal bolt F, inthe front end of the centre bar A, as shown.

' The latter', as also shown, are preferably connected with the side bars B, by vertical bolts b, being bifuroated, e, to receive the ends ofsaid bars, and' to engage with their attaching-bolts b, above and beneath them, being provided, 'at their Outer'l extremities, with pertbrations'e', at right angles to the plane of said boltsv b, for the reception of the pivotal pin G, in the rear end of the centre bar A.. f

The pins F G may be made of wrought-iron, and secured in any suitable manner. y The former is preferably provided with a suit-able head, j, and the latter screw-threaded on its outer end, and provided with. a

screw-nut, g, as shown.

The -provision'of the removable nut g, `ou the pin G, and the duplication of the perforations e', of the links E, as shown, may enable the Width of the rear end o'f the barrow to be adjusted, as desired, the vertical bolts b, and a slight elongation of the perforations in the ends d Of ythe front links D, serving to per- -mit the requisite movement of the side bars B.

Thevcoult'er H may be either a rolling one, as shown, or stationary, and, in either case, may be mounted inany usual or suitable manner, at the rear end of the centre bar A.

The handle I may be of Wood, andbe supported .by

tenon and mortise, or other s uitable connection, with' Y the centre bar A, and by the standard J, which may be of either metal or wood, as sbown.

Two handles may be employed, if preferred, and theirsupport varied, as required. By employing but one which is all that is. requisite, the sides of the frame are adapted to be more readily supported in an elevated position, out of the way of obstructions.

Tile clevis K` may be of cast or wrought-iron, of any suitable form, and attached in any proper manner, being arranged about one-third the length ofthe harrow, back from its front end, in the cent-re bar A, as.

Shown.

' The coulte H, projectingvinto the ground, serves to steady the movement of the barrow, and enable it to be accurately guided, its cutting characteristic ena bling it to cut through roots, 86e., which may lie in its path, and to more readily override such obstructions,

' as may not be thusA disposed of. Its 'mark may be utilized for laying off the ground. Its position at the rear end prevents its interference with the ready turning of the barrow, serving, rather, to facilitate this.

Ulaim.

I claim, as new- 1. The coulter H, arranged and employed substan- 4 tially as set forth. a

2. In combination with the coulter H, the handle I, as and for the purpose described.

3. The combination, in a barrow, of a frame, A B

B D E F G, teeth C, eoulter H, handle I, and clevis K, constructed and arranged as hereinrepresented and described, for the purposes set forth.

To the above specification of my improvements in harrows, I have signed my hand, this 29th day of June, A. D. 1869.

JOHN S. LEWIS.
